I have just created a custom AS3 Component to use in an MXML project.[code]but then i lose some re usability.What do i need to do to be able to set properties from mxml?
View 3 RepliesI am working on a custom Flex 4 component which is an aggregation of two existing flex components. I would like to be able to specify my own custom properties for the component as well as access the existing public subcomponent properties via MXML. For instance I might want to adjust the font color or style for the label and text input. toy component which aggregates both a label and a text input:

Is it wrong to access it like that. The PuzzlePiece is the export for a puzzle clip. For the time being I am hard coding the dimension as 60. I have aloso uploaded the fla and as files. [URL].
With MXML components, I've seen a pattern used where you have an AS3 class, then the MXML subclasses it, to have a separation between view/code (anonymized from real code):
package com.john
{
public class MyComponent extends Canvas
{
[code]...
At least I think the MXML component is subclassing the AS3 class?Anyway is it possible/advised to do this with my main MXML application file, so I can put manager instances and things in the AS3 MyApp class, which is subclassed by Main.MXML?
I can't use a "for in " loop to enumerate public properties of a custom class. So I have a class "ClassA" , which has some public properties. if I try :
PHP Code:
trace(classInstace.hasOwnProperty('property1'));// true
trace(classInstace.property1) // traces the property correctly
trace(classInstance.propertyIsEnumerable('property1')); // traces false ????
In AS2 we can not add methods n properties to built-in classes in the way we do in AS1. Like we would -say- write the custom "isNatural" method on the "Math" class as follows : * The following code is valid in AS1 but not in AS2
[Code]...
As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1. Later I came up with senocular' s very nice tutorial on OOP in AS2. And now i know how we can do it in AS2 style in an efficient n organised way. But i have a problem with the following code. It should not work ! but it does... * Following code is valid for both in AS1 and AS2.

How do I access Stage Class properties in Custom Class?

Output:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
i wonder why i am unable to access the public properties of this custom class the public var w:Number; and the Public var h:Number; i am tracing them and on an instance of the PreLoader() Class.. and ia m getting NAN;

View 2 RepliesWhat I'd like to do: create an MXML component with some children, then extend it via MXML to create a new component with more children, without losing the original set.In other words
create a component bc.mxml

I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.

So I have a movie clip associated with an external class in the linkage dialog. I put that movie clip on the stage. I have another external class that contains some code (not for the movie clip but for the stage). When I access the custom properties of the class in the actual flash file (not the external code) everything works fine.For example.myMovieClip.explodeTheCode = true;works in the main movie. However, it doesn't work in the external flash file when I have a reference to that movie clip.myRefToCustomMovieclip.explodeTheCode = true fails!It throws an error. In java, I'd just import the custom class the movie clip is linked to and then I can call all the extra custom methods on the movie clip in the external class I want. However, this does nothing. I still can't access any properties.So my question is, how do I access the custom features of a movie clip (that is linked to a custom class) from an external code file. It works in the movie, but not in the external source code.

My question is if i can define custom style names like dividerRightColor and if so, how can i use that value inside my MXML Component? I have seen examples of using them inside Pure AS components.
I have written "components" in external .mxml files like dialogs and such. For example, GamePropertiesDialog.mxml. These components are used by another file, Main.mxml for example. If I instantiate a GamePropertiesDialog I am unable to access its pieces like a textbox with an id of GameName until AFTER I add the dialog to the display list.Doesn't work:
Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();tmp.GameName.text = 'test';addChild(tmp);
Does work: Actionscript Code:
var tmp:GamePropertiesDialog = new GamePropertiesDialog();addChild(tmp);tmp.GameName.text = 'test';
If I do something like:
<myComponent id="foo" title="bar" />
The parameters don't seem to be available immediately within the component. When do they become available?
Is it possible to control the properties of 'advancedgridcolumns' in 'advanceddatagrid' mxml tag. For e.g. suppose the grid data provider has 3 different fields. Out of these 3 fields, one field is 'to_be_decided'. This field should not be displayed initially. Only the remaining 2 columns should be displayed (visible true) and the third column (one with data field as 'to_be_decided', visible flag will be false here ) should be hidden. It will be visible when some event like a button click or something is fired.
We can do this in action script coding by accessing individual columns of grid and taking appropriate actions. But will it be possible to do so in mxml? Is there some default property in grid that can be used here ?In mxml I can not access them individually in the grid (under tag) and hence I can not set the visible attributes individually for each of them. To add them one by one in 'columns' tags I would be required to know the data field in array collection and that I dont know. Only data field known is 'to_be_decided', rest two fields will vary time to time. Therefore even if I addd this one gridcolumn in 'columns' tag what about the other two?
Something like this :
<mx:columns>
<mx:AdvancedDataGridColumns dataField='to_be_decided' visible=false>
<!-- How to add other 2 columns here ? -->
</mx:columns>
I'm playing around with the scaleX/Y in the canvas tag and have noticed some strange behaviour. When I set scale in in mxml the width and height of the canvas are adjusted accordingly. For example if I have a canvas like this: <mx:Canvas width="1000" height="1000" scaleX="0.1" scaleY="0.1" />
The canvas now appears on screen to have a width and height of 100 and if inside my creationComplete callback I check the width and height property they are indeed 100. But if I do exactly the same thing except I set the scaleX/Y property from actionscript the canvas on screen appears to have a width and height of 100 as expected, but when I check the width and height property of the canvas they are still at the previous values of 1000.
i'm attempting to cast an object's property as an actual property of another object. here's my object variable: var propObj:Object = {prop:"width", width:50}; now i want to assign the property of a sprite using that object's properties. var sp:Sprite = new Sprite(); sp.(propObj.prop as Sprite.property) = propObj.width; now, i'm not even going to try that because i know the compiler will explode all up in my face. but you should be able to see what i'm trying to do. why i'm trying to do it is because i'm reading in an XML file with an undetermined list of usable properties for specific objects. so instead of writing something like a huge switch statement to evaluate whether the XML file has a value for that specific property, i'm trying to assign properties dynamically based on what's available in the XML file. if what i'm trying to do is possible, what's the best way to do it?
View 1 RepliesI'm completely new to this forum, and would like to ask your help for one issue. I am working on an interactive flash map, I was able to set all the countries borders with the help of fireworks (awesome tool), and import them back to flash and set each country as a button. I would like to set all of the buttons to have the same properties for example : All the buttons have default red color, and will have a mouse hover frame that will change the color of the button to blue. I DO NOT want to set each button manually, because I would like to have the choice to change the mouse hover color to a different one, and would like to avoid passing each button and changing each one's mouse hover frame.
Is there a way I can built a template of a frame, and for each button set its mouse hover frame as the template frame I built ? And then if I make any changes to the template frame, all of my buttons would be automatically updated ?
I want to open a new internet window using actionscript on a button but I also want to control the characteristics of that window when it opens:
1. I want it to be a specific size - 180 x 200
2. I want all the standard page elements removed - the scrollbar, browser tools etc - so there is just a box to close it.
3. I want it to be centered on the screen
Can I get this much detail with actionscript regarding the new window when I open it?
I need to assign a symbol that is added dynamically in a symbol, x and y coordinates (that are from the main timeline).

i've heard you shouldn't use eval anymore because it's deprecated, and that you should use this[object]._property instead, but it's not working for me--am i doing it wrong?

I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).
[Code].....
When I define custom propertie in my MXML component, I also want to define a set of possible values of that property to make Flex Builder show then (possible values of the custom property) when I invoke code completion function.
